This is GIFgraph, a package to generate GIF charts, using Lincoln Stein's GD.pm. INSTALLATION needed to install (also see TESTED PLATFORMS): perl 5.004 GD > 1.14 to install: perl Makefile.PL make make test make install NB: If you don't use the same version of GD that I have (1.18), some of the tests may fail (specifically, the area test). You should be able to ignore this failure, if the samples files give you good results. IOW: Check the samples in the samples directory. If they look good, then GIFgraph will work fine. to see some samples: cd samples make That should generate a set of gifs, which you can view using the HTML pages in the same directory (or whichever other way pleases you). The documentation available is contained in GIFgraph.pm, as pod. The latest release should normally be available from CPAN and from http://www.tcp.chem.tue.nl/~tgtcmv/perl/ TESTED PLATFORMS (also see NOTES FOR WIN32) - perl 5.004_04 on Solaris 2.5.1, GD 1.15 - perl 5.004_04 on Solaris 2.6, GD 1.18 - perl 5.005_01 on Solaris 2.6, GD 1.18 - perl 5.004_02 for win32 by Gurusamy Sarathy, GD (1.14 I think) - perl 5.004_04 HP-UX 10.20, GD 1.18 (Ronald Post) AUTHOR Martien Verbruggen mgjv@comdyn.com.au tgtcmv@chem.tue.nl MOST IMPORTANT CHANGES SINCE VERSION 1.01 - Vertical printing of X axis labels - CHANGED DEFAULTS for zero_axis and zero_axis_only - Fixed problems with negative values, data ranges without 0, and printing of the x axis labels (I hope) - No more support for perl 5.003. Since perl 5.005 is out, and I don't have a 5.003 here to test all the time, I won't support it anymore. MOST IMPORTANT CHANGES SINCE VERSION 0.91 - Legends - Support for negative numbers - Ticks for X axis - line types and widths - Allow entries in data set to be undef (to skip them) - Changed 'zero' angle for pie charts (was right, now is front/bottom) - Definition of colours now possible. See GIFgraph::colour::read_rgb for details - See file CHANGES for more TODO - 3d look for graphs - logarithmic scaling - numerical X axes - Autoloading/splitting, etc - More options, split up some options. - Mixed Graphs - Better preset options for certain graph types BUG FIXES IN THIS VERSION See file BUGS NOTES FOR WIN32 GIFgraph installs and runs well under Gurusamy Sarathy's port of perl for win32, and its usage is exactly the same as documented. The ActiveState port for win32 can be used with Dave Roth's port of GD for win32. This port, however has a peculiarity. It is impossible to manipulate the gif data in memory (the GD::Image::gif() method always writes to a file descriptor, instead of returning the data). This makes the use of GIFgraph with that port impossible without a lot of work. This means that until someone ports GD for the ActiveState perl with full support for all its functionality, GIFgraph will not work on ActiveState's port.
